Canon low pass filter explanation

Dennis Hissink : 2005-02-17 12:00:00
Canon low pass filter explanation : Certain fabrics can have a very tight, regular weave. On close inspection, this can appear as a series of alternating stripes separated by dark shadows between the weave. When the pitch of this weave is close to a digital camera sensor's pixel pitch, light from the subject will only activate selected rows of pixels. The sensor will then produce false colours, which can change with rotation or lateral movement of the camera. These false colours appear as waves on the image, known as moiré. Subjects such as distant geometric patterns are also susceptible to producing this effect. To combat the effects of moiré, camera manufacturers sometimes utilize a low pass filter to blur incoming light.

Samsung eight-die Multi Chip Package introduction

Dennis Hissink : 2005-01-17 02:00:02
Samsung eight-die Multi Chip Package introduction: Samsung announced that it has developed the world's first eight-die multi-chip package (MCP) technology, designed for use in high capacity mobile devices such as 3G handsets and other increasingly smaller mobile devices. As the number of chips per memory package increases, so does the thickness of the package. Using its Wafer Supporting System technology to makes wafers thinner during design processing, Samsung has been able to minimize overall chip thickness as well as decrease the space between the stacked dies. As a result, the eight-die MCP solution offers an unmatched combined capacity of 3.2Gb in a package that is 1.4mm thick, equalling the thickness of a four-die MCP solution.


CompactFlash specification revision 3.0 approved

Dennis Hissink : 2005-01-14 23:45:05
The CompactFlash Association (CFA) announces the approval and availability of the CF+ & CompactFlash Specification Revision 3.0. Revision 3.0 increases the CompactFlash interface data transfer rate from 16MB/sec to 66MB/sec, while maintaining forward and backward compatibility with old and new host systems. Mr. Shigeto Kanda of Canon and the CFA chairman of the board said: "The development of the CompactFlash 66MB/sec interface means that the CompactFlash interface will not restrict the sustained data transfer rate of CompactFlash cards in the near future. Having the fastest interface data rate of any flash cards is a significant step for CompactFlash."
